Despite various improvements and progress in the field, some of the major obstacles that still exist, involve having a specific number of buttons to perform a set of given functions. This leads to higher manufacturing cost since several components are involved. Also the assembling and manufacturing effort is more.
Another major limitation of existing prior art is that since the position of control buttons on the device is fixed, it is not user friendly from the perspective of left handed person or right handed person. Many of the devices have the buttons located centrally which is inconvenient for one handed operation, which is currently what most people use to operate devices like smartphones. According to the make/design of the smartphone, different protective casings are required which have the necessary openings or adaptations to accommodate the side buttons. Many times in order to accommodate different functional features, several control buttons have to be pressed together or in a combination, which can be quite cumbersome for a user.
Accordingly, improvements are needed in the existing methods and structures that negate the above shortcomings in the existing systems.
The purpose and methodology of all the above inventions that are part of prior art do not envisage the unique embodiment of an electronic device with slidable control buttons, thus eliminating fixed buttons located on the sides of the electronic device for various functions such as controlling volume, power on and off, vibrational mode, which also reduce the cost of manufacturing and facilitate easy one hand operation for a user.
